  • Energy Recovery in Urban Wastewater Treatment on Global Scale

    ABSTRACT The lack of proper wastewater treatment results in production of CO2 and CH4 without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO2 and CH4 emissions associated with wastewater discharges could reach the equivalent of 3.13·105 tCO2·d-1 in 2025, with ...

  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Energy recovery from the Exhaust gases of a Cyclone preheater tower - case study

    FOREWORD Advanced Cyclone Systems, S.A. (ACS) designed and supplied a Hurricane cyclone system for Duna-Drava Kft cement plant in Beremend, Hungary, (a member of the HeidelbergCement Group, the global market leader in aggregates), as part of an energy recovery project. To maintain the quality of the ground Pet Coke within the specifications in terms of ash content, ACS was contacted with the ...

  • Plasma resource recovery technology –converting waste to energy and valuable products

    Abstract Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired ...

  • Monroe Scrubbing System provides halide recovery at a major glass products plant

    Challenge A glass manufacturing plant was having trouble cleaning the emitted gases, particulate, and odors that resulted from its manufacturing process. Metallic Halides such as SnCl4 and TiCl4 were being applied to hot glass to impart special properties. The halide and oxide emissions were hazardous, extremely pungent, irritating in odor, and very difficult to scrub. ...

  • Replacing of mechanical compressors by gas ejectors in flare gas recovery systems

    One of the main concerns of humankind in this century is the global warming induced by the increasing concentration of greenhouse gases in the atmosphere.
